ajax调用webservice jquery代码实例

//无参数调用

$(document).ready(function() {
$('#btn1').click(function() {
$.ajax({
type: "post", //访问webservice使用post方式请求
contenttype: "application/json", //webservice 会返回json类型
url: webserviceurl + "webservice1.asmx/helloworld", //调用webservice的地址和方法名称组合 ---- wsurl/方法名
data: "{}", //这里是要传递的参数，格式为 data: "{paraname:paravalue}",下面将会看到
datatype: 'json',
success: function(result) { //回调函数，result，返回值
$('#dictionary').append(result.d);
}
});
});
});

//有参数调用
$(document).ready(function() {
$("#btn2").click(function() {
$.ajax({
type: "post",
contenttype: "application/json",
url: webserviceurl + "webservice1.asmx/getwish",
data: "{value1:'心想事成',value2:'万事如意',value3:'牛牛牛',value4:2009}",
datatype: 'json',
success: function(result) {
$('#dictionary').append(result.d);
}
});
});
});

//返回集合（引用自网络，很说明问题）
$(document).ready(function() {
$("#btn3").click(function() {
$.ajax({
type: "post",
contenttype: "application/json",
url: webserviceurl + "webservice1.asmx/getarray",
data: "{i:10}",
datatype: 'json',
success: function(result) {
$(result.d).each(function() {
//alert(this);
$('#dictionary').append(this.tostring() + " ");
//alert(result.d.join(" | "));
});
}
});
});
});

//返回复合类型
$(document).ready(function() {
$('#btn4').click(function() {
$.ajax({
type: "post",
contenttype: "application/json",
url: webserviceurl + "webservice1.asmx/getclass",
data: "{}",
datatype: 'json',
success: function(result) {
$(result.d).each(function() {
//alert(this);
$('#dictionary').append(this['id'] + " " + this['value']);
//alert(result.d.join(" | "));
});
}
});
});
});
//返回dataset(xml)
$(document).ready(function() {
$('#btn5').click(function() {
$.ajax({
type: "post",
url: webserviceurl + "webservice1.asmx/getdataset",
data: "{}",
datatype: 'xml', //返回的类型为xml ，和前面的json，不一样了
success: function(result) {
//演示一下捕获
try {
$(result).find("table1").each(function() {
$('#dictionary').append($(this).find("id").text() + " " + $(this).find("value").text());
});
}
catch (e) {
alert(e);
return;
}
},
error: function(result, status) { //如果没有上面的捕获出错会执行这里的回调函数
if (status == 'error') {
alert(status);
}
}
});
});
});

//ajax 为用户提供反馈，利用ajaxstart和ajaxstop 方法，演示ajax跟踪相关事件的回调，他们两个方法可以添加给jquery对象在ajax前后回调
//但对与ajax的监控，本身是全局性的
$(document).ready(function() {
$('#loading').ajaxstart(function() {
$(this).show();
}).ajaxstop(function() {
$(this).hide();
});
});
